CHINCH-BUG KILLER.

Application filed June 19, 1919.

T0 all w kom t may concern Be it known that i, .lor-rn '11. PnRniNes, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a new and useful Chinch-Bug Killer, of which the following is a specification.

The invention relates to appliances for killing chinch bugs or other insects which are destructive to crops. rli`he general purpose of the invention is to provide means whereby a vaporizable substance, which is in its nature destructive to insect life, may be used to destroy insects without danger to the person using it; and to provide simple and effective means for controlling the ap nlication of the insecticide.

f ther purposes of the invention are:

To provide a light and strong supporting' structure; to provide a container for the destructive substance; to provide a removable closure for said container; to provide a heat-controlled instrument,V for operating said closure; to provide means for applying moderate heat to said instrument, and to provide other new and useful structural details. v

The invention is illustrated in the annexed drawings, to which reference is hereby made, and will now be described and the novel features thereof will be recited in the claims. Y

Figure 1 is a front elevation of an apparatus embodying my invention; Fig. 2 is a rear elevation of part of the same apparatus; Fig. 3 is an oblique section on the line 3-3 of Fig. l; Fig. 4 is a horizontal transverse section on the line 4 4 of Fig. 1; Fig. 5 is a perspective view of the closure latch; 'and Fig. 6 is a reduced perspective view of the detached frame of the apparatus. The same reference numerals designate the same parts in all the views.

The frame supporting the several parts of the apparatus is preferably of stiff wire, bent to form a vertical leg 1, horizontal feet 2, a shoulder 3, an eye 4, and an inclined le 5.

tuThe metal bed-plate has a'transverse hole 8 accommodating the cylindrical container 9; and a transverse hole 10 accommodating the cylindrical generator 12. A set screw 13 secures the container in place in the bedplate; and a set screw 14 secures the generator in place in the bed-plate. The container and the generator are detachable Speeication of Letters ratent. Pttgnted ltty 1Q, 1921.

from the bed-plate for convenience in filling them; and also to admit of compact storing of the parts for transportation.

The container 9 is a meta-l cylinder closed at one end and having at its open end an integral flared circular flange 15. The open end of the cylinder i finished flared so that the inner face of the closure 16 will have air-tight contact with the flared end of the cylinder'.

The closure 16 is a circular metal plate having its circumference finished to seat in the flared end of the container, also having a central boss 17 having a transverse groove V18. When the closure 16 is in place in the stationary in one end of the tube 12; a

screw V26 screwing into the extension 25; a gasket 27 between the head of the screw and the outer end of the extension and forming in conjunction with the screw a gas tight closure at one end of the tube; and a stopper 28 preferably of cork or rubber, fitting tightly in the other end of the tube and forming a gasv tight closure at that end of the tube. A hook-29 screws into the stopper 28 and when the parts are assembled, as shown in Figs. 1 and 3, the hook 29 bears irmly on rod 20, and the rod occupying the groove 18 in the boss 17 presses against the boss 17 to hold the closure'l firmly in the fiared end of the container 9. The tube 12 is preferably of thin metal which would likely be injured by cutting screw threads on the inside of the tube; the extension 25, of thicker metal, is therefore used and is brazed or soldered in the tube as a matter of convenience in manufacture. The screw 26 may be removed forcharging or cleaning the generator.

The generator is designed to contain a material which under the influence of mild heat, applied for a considerable time on the outer surface of the tube, will generate a gas having suflicient explosive energy to violently expel the stopper 28. I prefer to use the material known as mustard gas, but any other suitable material having the properties stated may be used without departure from my invention.

The heater comprises a tube 30 ot' thin metal, having a hook 3l which hooks around the generator tube l2 to support the heater directly under the generator. A spring movable vertically within the tube 30, clasps a stick of punk 32, and admits et vertical adjustment'ot the punk within the heater to control the heat as may be required.

To prevent waste or the substance discharged trom the container 9, I provide a pan 6 to contain the appliance and receive the discharged substance.

The substance used in the container being of a kind which might be deleterious to the user of the appliance, I provide the latch 2l as a safeguard against untimely discharge of the contents et the container, and I provide means Jfor very slow heatingof the generator, so that the user may have ample time to leave the place where the appliance is being used before the contents ot the container can be released and become etfective.

The substance used in the container and the material used in the generator are prepared under special formulas; inasmuch however, as this application relates solely to mechanical appliances for utilizing` said substance and said material it is deemed unnecessary to herein recite more clearly than has already been done the nature and properties orn said substance and said material.

.The mode of operation oi.E the appliane is as follows: rllhe container 9, will be iirst illed with the insecticide substance and closed and the closure 1G secured by the latch 2l. The rod 20 will then be placed in the groove 1S of the boss 17 and the tree end ot the rod will be pressed against the end otl the stopper and upward under the hook 29 and the red bearing against the hook and the boss will hold the closure firmly in the end ot' the container. Immediately before using,r the screw 2G will be removed and the generator will then be partly filled with the gasgenerating material and the screw will be replaced and the latch 2l may then be safely removed by hand.

The apparatus will then be placed in the pan 6 and the pan will be placed where the apparatus is to be used. The heater 30 will then be hung on the cylinder l2 and the punk lighted.

In due course of time. say about twenty minutes, the slowly burning punk will have heated the generator to such extent that the material in the generator will have produced enough gas to blow out the stopper 29 and thereby cause the rod 2O to pull the closure 1G away from the container 9, to permit the contents et' the container to fall into the pan G, to be vaporized there and gradually applied on and around the crop infested by the chinoh bugs or other insects and thus destroy the bugs or insects.

I do not restrict my claims to the precise details ot construction herein set forth,

since it is obvious that minor details may bevaried without departure from my invention. y

lffhat I claim as new and desire to secure by Letters Patent is:

- l. In an appliance or" the class described, the combination of a container; a removable closure closing the container; a generator' adjacent to the container; a propulsive stopper closing one end ot the generator; and a connecting device operatively connecting the propulsive stopper ot the generator with the removable closure et the container.

2. In an appliance of the class described, the combination of a container; a closure ,closing` the container; a `generator adjacent to the container; propulsive closure closing the generator; means operatively connecting said closures, and means for applying mild heat to the generator to cause ejection oi said propulsive closure.

3. In an appliance ot the class described, the combination of a container having a circumferential flange; a closure seating in one end oit the container and having a central boss; and a safety latch having a notch to accommodate the boss ot the closure and having members engaging the circumferential flange ot the container.

4. In an appliance oi the class described, the combination ot a pan; a stand in the pan, a bed-plate supported by the stand; a container on the bed-plate; a closure closing the container; and means for removing the closure to cause the contents of the container to vtall into the pan.

In witness whereof I have hereunto signed my naine at Springfield, Illinois, this 4th day of June, A. D. 1919.
